Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth.

Middle latitude cyclones are fueled by air high in the atmosphere.

The troposphere is the lowest layer of the atmosphere and where most clouds are. That means all weather is in the troposphere. Almost all weather occurs in the Troposphere, basically, the lowest layer that goes up to about 10 - 15 kms.

5% of 4000

= 5 x 4000/100

= 5 x 40

= 200

Hence, 5% of 4000 = 200.

Phage typing is based on the fact that bacterial viruses attack specific cells. Phage typing is a method used for detecting single strains of bacteria. It is used to trace the source of outbreaks of infections. 

The three statements make up the cell theory are::

1. All living things are made up of cells.

2. Cells are the basic unit of structure/function in living things.

3. New cells come frome exisiting cells.

These cells can vary widely, but all living things are composed of cells.

Most of the emissions of greenhouse gases (GHG) come primarily from burning fossil fuels (coal, hydrocarbon gas liquids, natural gas, and petroleum) for energy use and the major greenhouse gas is of course carbon dioxide (CO2) which comes from burning fossil fuels and land-use change.

But methane (CH4) and nitrous oxide (N2O), which mostly come from agriculture and waste, are also significant GHGs and shouldn't be discounted.

Business cycles are identified as having four distinct phases:

1. Expansion,

2. Peak,

3. Contraction, and

4. Trough.

Expansion is the phase of the business cycle when the economy moves from a trough to a peak. It is a period when the level of business activity surges and gross domestic product (GDP) expands until it reaches a peak. A period of expansion is also known as an economic recovery.

An expansion is characterized by increasing employment, economic growth, and upward pressure on prices.

Water is capable of dissolving a variety of different substances, which is why it is such a good solvent.

And, water is called the "universal solvent" because it dissolves more substances than any other liquid

It means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients
